So no need to worry about this worm? Where would it have come from? I have had my tank set up for about 4 years and have not gotten any new rock or any thing... also my tank now has a million baby star fish. Should I be concerned about those?
I was looking at my tank yesterday and noticed this thing crawling out of one of my rocks... does anyone know what this is and if it is a good or bad thing in there?
